To. all whom it moby concern,.- -Be it known that I, MORSEB. citizen of the United States, residing at St.

a new and useful Improvement in Car-Trucks, of which the following is a specification.

My invention relates and the center-bearing six-.wheel passenger-car truck.

Usually the center-bearing wood combined with sandwichwise in the beam andv secured thereto by bolts.I To .the 'center-bearing beam the center plate is secured by bolts. By this construction' the center-bearing 4beam shrinks and 'splits and becomes warped, thereby causvand fastenings of iron in the construction of the center-bearing beam and center plate inflexible, and durable center-bearing beam and -center plate integral throughout. 4 l

The invention consists in features of novelty hereinafter described and claimed, reference being had to the accompanying drawings, forming part of this specicatiomwhereon ,Y f Y Figure 1 is a planof my improved centerbearingbeam and center plate as applied to a six-wheel passenger-car truck; Fig.f2, a longitudinal vertical section lthereo' the combined .parts of the car-body; Fig. 4, a side View, to enlarged scale,

-Referring to Figsrl, 2,'and`- 3, A represents a six-wheel passenger-car truck having myv improved center-bearing beam a, and' center plate `bapplied thereto, but otherwise simi-.55 lar'in-allits parts to an ordinary six-wheel passenger-car truck. t 4

lMy improved center-bearing beam a. and center plate b, as' shown particularly in detail in Figs. f4, 5, 6, 7*, `8, and 9, in'lieu separate parts bolted together, as in the ordinary construction, ar'e cOmbin'ed'in/'a singlev piece composed, preferably, of cast-steel having lon top a concavity 1,fro1n which projects upwardly al central circular hub 2, the 'con- 65 cavity 1 and hub2 constituting the truck center plate b for' engagement with the corresponding convex portion 3 and central recess 4, respectively, of the car-bodyl'center plate t c, as in the ordinary construction of center 7o plates.- Throughthe recess 4 and hub 2`of" the center plates cb are holes' 6, respectively, n through which passes the king-bolt 7 in the usual manner. t

The body of the center-bearing beam and 7 5 center plate a b may be of any desired section Y and configuration, such as an inverted U shape in cross-section, as shown, the parallel sides- 8 of' the body having strengtheningbrackets 9 and having,preferably,at each end, 8o respectively, a rectangular box-shaped columnar enlargement 10, which is closed at the top and bottom to form bearings 11 l2, respectively, for-the top and bottom center-bearing l arch-bars 13 14,which carry the center-bearing 8 5 beam and center plate a; b and are secured to the enlargements 10 by the bolts 15which pass vertically through the arch-bars 13 14 'and enlargements 10,. as shown. Each bearing '11 12 is formed longitudinally with two opposite 9o side anges l'for laterally holding the archbars 13 14 in position. o v v 4Fortakin'g upthe Wear of the center plates b .c and the settling of the car-body, due to the sagging or setof the arch-bars, I use prefer- 95 ably two or more shimming or adjusting plates d, of iron and of varyingthickness, vwhich'initiallyare assembled and placed be-' tween the top'bearings 11 and the top-center-bearing arch-bars 13, and in that position ro'o support the car-body at its normal height or so that the body side bearings e are clear of taken on platek dk is removed from between the top bearthe truck side bearings f, as seen in Fig. 2.

As the car-bodyfdrops'one ofthe shimming-f f and the bottom center-bearing' arch-bars 14,

thereby lowering the arch-bars 13 14 and with themr the spring-beams g andtruek side bearo ings f, and

so restoring the proper clearance between the side bearings ef. On further settling of '.the car-:body anothershimming-y ings 11 and arch-bars 13 and placed with the -first-named plate el between the bottom bear-y lngs lowering the truck side bearingsf andso on as often as necessary to adjust the ylevels 'of the side bearings ef.

y,As shown in thedrawings, the bolts 15 preferably pass through 'holes 17 therefor inthe shimming-plates d, whereby the plates dare Iirmly held in position.

kThe various parts hereinbe'fore specifiedto wit, the center-bearingbearn a,h`aving`the bearings 1112 andffianges 16 for the arch-bars 13 14 andk havingthe strengthening-brackets 9, with the center plate b, having the hub 2 are integral throughout, the whole forminga' f i f f strong inflexible structurewithout the use of 12 and arch-bars 14, thereby still furtherk 'separate stiiening-pieces, bolts, and fastenings. f f

What I claim as myk invention, and desire n K to secure by Letters Patent, is-

f 1.y Ina car-trucha ycenter-bearing beam having integral therewith thek center plate and at the ends the columnar enlargements r10 formed with bearings, 11 and 12.i f

2. In a car-truck a transverse center-bearingbeam having integraltherewith the center plate and at the en'ds'the columnar enlargements 10 formed with bearings 11 and 12, combined with the longitudinal arch-bars and the` adj listing-plates in said bearings.

In a six-wheel passenger-car truck, the

combination withy the spring-,beamy havingthe f side bearings secured thereto, of a centerbearing beam having its center plate integral therewith, and having integral therewith yat f f its ends columnarenlargements formed with bearings, and the center-bearing arch-bars engaging said bearings and co'n'nectedwithy the spring-beams.
